Perkins Ellie Dart Daren Kaiser Developmental Psychobiology ABSTRACTPrenatal alcohol exposure (PAE) can lead to a wide range of adverse effects in humans, including impaired self‐control and increased impulsive behavior. Deficits in self‐control can interfere with academic performance and have lasting impacts. In the present study, a rodent model of PAE was used to assess impulsivity through operant conditioning. Pregnant rats were assigned to one of three groups: ad‐lib control (CON), pair‐fed (PF), and alcohol‐exposed (ALC). ALC rats were given a liquid diet containing 6% alcohol, PF rats were yoked to an ALC rat and given a CON liquid diet, and CON rats received ad libitum food. Operant conditioning was used to evaluate extinction in adolescents (Experiment 1) and differential reinforcement of low rates (DRL) in adolescents and adults (Experiment 2). PAE resulted in an increase in responses and resets during DRL testing, indicative of impaired self‐control, an effect that was only observed in adolescent males. Females, regardless of age, did not show increased impulsivity following PAE. This indicates that children with PAE may exhibit attentional deficits similar to those with attention deficit hyperactivity disorder, with males at a higher risk. 10.1002/dev.22555 http://creativecommons.org/licenses/by/4.0/ |
